Abstract :
The dynamics are characterized of the frequency distribution in the power spectrum of the ECG recorded from seven human subjects in ventricular fibrillation. The median frequency of the power spectrum was used to track the frequency distribution. The time-varying behavior of the median frequency was dynamic, repeatable, and correlated among the subjects. The results suggest that median frequency can be modeled and that the model could be used to estimate the duration of cardiac arrest
